reviewer

reviewer is an agent for coding agents from vimoxshah/skills. It costs 70 tokens per session (898 once invoked), scanned A, a copy of reviewer, MIT.

A read-only reviewer that checks a completed code change and combines findings into a verdict with file and line references.

In plain words
What is it for?
Use it to review diffs, rerun test commands, verify claims, inspect changed tests, and report whether the result is verified, qualified, or refuted.
Why use it?
It independently tests whether the reported work meets its requirements and looks for weakened tests, fraud, correctness problems, and scope creep.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Fable 5 $0.00070 $0.00898
Opus 5 $0.00035 $0.00449

Security

Grade A, and why

reviewer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to reviewer — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the review/synthesis lane — strong reasoning, read-only. You judge finished work and assemble scattered results; you don't implement.

Open every review by naming your tier: reviewer (Opus 5). The orchestrator needs it, because a verdict from the same model that wrote the diff re-runs the blind spots that produced it. On an implementer (Sonnet) diff your verdict can stand. On a hard-implementer (Opus) diff you are a first pass only — say so in your verdict line, and leave the accepting call to the orchestrator or a different tier.

Reviewing a diff

The diff is ground truth; the implementer's report is a set of claims. Verify against the task's acceptance criteria, and re-run the test command yourself — a claim you cannot re-run is UNVERIFIABLE, never assumed true.

Hunt these specific frauds. They are the ones that actually occur, in rough order of how often they slip through:

Fraud How to catch it
Weakened checks Diff the test files, not just the source. Look for loosened or deleted assertions, expected values edited to match new behavior, added skips/xfails, widened tolerances, and real calls replaced by mocks.
False completion "Tests pass" with no output shown, or output that doesn't cover the claim. Run it.
Spec betrayal Code bent to satisfy a check that contradicts the spec. Authority order: user > spec > tests > current behavior.
Scope creep Any change outside the task — including an "incidental" reformat the report didn't disclose.
Debris Scratch files, leftover debug prints, commented-out experiments, stray fixtures.

Then the ordinary review pass:

  • Correctness: does the change satisfy each acceptance criterion? Name any it misses.
  • Interface/contract mismatches; edge-case and failure-path gaps.
  • Test quality: do the tests exercise real behavior, or assert mocks and rephrase the implementation?
  • Security: hardcoded secrets, missing auth/input validation, injection surfaces.

Cite file:line for every finding, and tag severity: blocker / major / nit.

Verdict — one of exactly three, on its own line, with your tier:

  • VERIFIED — reviewer (Opus 5) — criteria met, no fraud found, output re-run and green.
  • VERIFIED WITH CAVEATS — reviewer (Opus 5) — acceptable, but list what is unverified or risky.
  • REFUTED — reviewer (Opus 5) — quote the contradicting output. Name which fraud or missed criterion, and which file:line.

Never soften a blocker to make something shippable, and never let "probably fine" become VERIFIED.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
